FAP inhibitors

ABSTRACT

The present invention concerns compounds, according to general formula (I), which find utility preferably for the treatment of cancer.

FIELD OF THE INVENTION

The present invention relates to compounds, which act as FAP inhibitors, pharmaceutical products comprising the compounds, and methods of treatment using the compounds.

BACKGROUND

The enzyme fibroblast activation protein alpha (FAPα), herein abbreviated FAP, is a serine protease that possesses dipeptidyl-peptidase activity specific for N-terminal Xaa-Pro sequences. In addition to the dipeptidyl peptidase activity FAP also possesses collagenolytic activity capable of degrading gelatin and type I collagen. FAP is a type II transmembrane serine protease which is expressed as a homodimer. The 95-kDa protein exhibits 48% amino acid identity with DPIV and displays structural similarity to other members of the dipeptidyl peptidase family including DP8 and DP9. Unlike DPIV, FAP has also been reported to possess endopeptidase activity (Aertgeerts, J. Biol. Chem., 2005, 280, 19441). FAP overexpression has been shown to potentiate tumour growth (Cheng, Mol. Cancer. Ther., 2005, 4, 351), and this potentiation is dependent upon its enzymatic activity. Natural substrates for FAP have not yet been identified. FAP is not expressed by normal mature somatic tissues and benign epithelial tumours but is expressed on stromal fibroblasts in more than 90% of carcinomas including breast, colon, ovarian, bladder and pancreas (Garin-Chesa et al., Proc. Natl. Acad. Sci., 1990, 87: 7235) as determined by immunohistochemistry, making this a very specific target for potential anti-tumour agents. Expression of FAP has also been correlated with invasive potential of melanoma cells (Aoyama et al., Proc. Natl. Acad. Sci., 1990, 87: 8296) and its presence has been associated with metastasis of colorectal tumours (Iwasa et al., Cancer Letts., 2003, 199: 91). Its presence has been shown to increase tumour formation in animal models (Cheng et al., Cancer Res., 2002, 62: 4767).

The catalytic action of FAP expressed in stromal fibroblasts in carcinomas has been utilised in the conversion of prodrugs of cytotoxic or cytostatic drugs to active drugs as a potential treatment for cancer (EP 1333033).

In addition to its activity in tumour tissue FAP is also expressed in organs undergoing non-malignant remodelling, for example liver fibrosis (Levy et al., Hepatol., 1999, 29: 1768). In patients with fibrosis as a result of alcohol abuse or viral challenge, the cells responsible for the excessive scarring and constriction of the liver express large quantities of FAP. There is evidence to suggest that FAP plays an important role in the formation of the fibrotic scar.

Normal tissue is normally FAP negative, however, it is found transiently in healing wounds (Ramirez-Montagut et al., Oncogene, 2004, 23, 5435) and it is possible FAP plays a role in tissue remodelling and repair. Other potential indications for FAP inhibitors include blood cell disorders such as anemia and chemotherapy-induced neutopenia (Rosenblum et al., Curr. Opin. Chem. Biol., 2003, 7, 496).

The only FAP inhibitor reported to date is ValboroPro (PT-100, Talobostat) which has been reported to show potent anti-tumour activity in mice, slowing growth of syngeneic tumours and causing regression and rejection of tumours after oral administration (Adams et al., Cancer Res., 2004, 64: 5471). This compound is currently undergoing clinical trials as a treatment for cancer (McIntyre, Drugs of the Future, 2004, 29, 882). However, this compound, which is a non-specific inhibitor of dipeptidyl peptidases, has been shown to be a potent inhibitor of DPIV (Coutts et. al., J. Med. Chem., 1996, 39, 2087). It has been demonstrated (Cheng, Mol. Cancer Ther., 2005, 4, 351) that FAP-driven tumour growth can be attenuated using ValboroPro; this effect is unlikely to be due to DPIV inhibition suggesting that FAP plays an important role in the promotion of tumour growth. ValboroPro has also been shown to stimulate the growth of hematopoietic progenitorcells and to accelerate neutrophil and erythrocyte regeneration, this regeneration was observed in DPIV knock-out mice (Jones, Blood, 2003, 102, 150).

Inhibitors of DPIV are at present in clinical trials for treatment of type II diabetes. Of the many reported inhibitors of DPIV one class of compound reported are the aminoacyl pyrrolidine nitriles (Evans, IDrugs, 2002, 5, 577). However, these fall into two distinct classes; those with an unsubstituted amino group at the N-terminus (WO 9515309, WO 0181337, WO 0181304), and the N-allylglycine derivatives (WO 0196295). No data has been reported for the activity of these compounds as FAP inhibitors. There are no reports of DPIV inhibitors with an N-acyl or N-carbamoyl N-terminus.

Whilst inhibitors of prolyl ologopeptidases (which have endopeptidase activity) are known, they appear not to have been reported as showing any activity against cancer in clinical testing.

According to an aspect, the present invention aims at providing active, selective FAP inhibitors, preferably without DPIV inhibition. Preferably, the compounds are easy to synthesize. More preferably, they are orally available.

Representative examples can be found in “Handbook of Pharmaceutical Excipients”; Ed. A. H. Kibbe, 3^(rd) Ed., American Pharmaceutical Association, USA and Pharmaceutical Press UK, 2000.

The compounds of the present invention can be prepared by methods generally known in the art and illustrated in the following non-limiting examples.

The compounds according to general formula 1 can be prepared using conventional synthetic methods.

In a first step (Scheme 1) a nitrogen containing heterocycle (5) is coupled using standard peptide coupling conditions to an alpha amino acid (6) suitably amino-protected with a standard protecting group such as tert-butyloxycarbonyl (BOC), benzyloxycarbonyl (Z) or 9-fluorenylmethyloxycarbonyl (Fmoc). The use of such groups is well known in the art. Where R1 has a reactive functional group such as an amine or a carboxylic acid, this group will also be protected. The principles of functional group protection are well known in the art and are described in, for example, J. F. W. McOmie, “Protective Groups in Organic Chemistry”, Plenum Press, 1973; T. W. Greene and P. G. M. Wuts, “Protective Groups in Organic Synthesis”, 3^(rd) edition, John Wiley, 1999; and P. J. Kocienski, “Protecting groups”, Georg Thieme Verlag, 1994.

In a second step when the group A of 7 is a carbamoyl group this is dehydrated to the corresponding nitrile using standard dehydrating conditions such as trifluoroacetic anhydride, or phosphorous oxychloride in pyridine or DMF (Scheme 2). Deprotection using standard methods followed by reaction with an acid chloride or isocyanate in the presence of base gives the compounds of the invention. Alternatively such compounds may be prepared from the deprotected compound by coupling the amine with a carboxylic acid using standard coupling conditions or reacting the amine with a further amine in the presence of CDI or phosgene or diphosgene.

Alternatively in a second step the intermediate 7 can be deprotected using standard methods and reacted with an acid chloride or isocyanate in the presence of base (Scheme 3). Alternatively such compounds may be prepared from the deprotected compound by coupling the amine with a carboxylic acid using standard coupling conditions or reacting the amine with a further amine in the presence of CDI or phosgene or diphosgene.

When the group A of 8 is a carbamoyl group this is dehydrated to a nitrile using standard dehydrating conditions such as trifluoroacetic anhydride, or phosphorous oxychloride in pyridine or DMF giving the compounds of the invention (Scheme 4).

When the group A of 8 is a hydroxymethyl group this is oxidised to an aldehyde 9, using an oxidising agent such as Dess Martin Periodinane giving the compounds of the invention (Scheme 5).

The aldehyde 9 can be further manipulated to give ketones (Scheme 6). This involves reaction of the aldehyde with organometallic reagents such as Grignard reagents or lithiated aromatics and heteroaromatics and the subsequent oxidation of the resulting alcohol using an oxidising agent such as Dess Martin Periodinane giving the compounds of the invention.

An alternative route to the ketones starts from a nitrogen containing heterocycle-2-carboxaldehyde suitably amino-protected with a standard protecting group such as tert-butyloxycarbonyl (BOC), benzyloxycarbonyl (Z) or 9-fluorenylmethyloxycarbonyl (Fmoc). The use of such groups is well known in the art. In a first step the aldehyde is reacted with organometallic reagents such as Grignard reagents or lithiated aromatics and heteroaromatics (Scheme 7). The protecting group is removed by standard methods giving compound 10.

An alpha amino acid suitably carboxyl-protected with a standard protecting group is reacted with an acid chloride or isocyanate in the presence of base (Scheme 8). Alternatively such compounds may be prepared from the deprotected compound by coupling the amine with a carboxylic acid using standard coupling conditions or reacting the amine with a further amine in the presence of CDI or phosgene or diphosgene. The carboxylic acid is protected as an ester such as methyl, benzyl or tert-butyl. The use of such groups is well known in the art. Where R1 has a reactive functional group such as an amine or a carboxylic acid, this group will also be protected. After deprotection using standard methodology the resulting acid is coupled with the amine 10 using standard coupling methodology. Subsequent oxidation of the resulting alcohol using an oxidising agent such as Dess Martin Periodinane gives the compounds of the invention.

When the A group of 8 is a boronic acid this is protected as an ester by protecting groups described in the literature such as pinanediol esters. This protecting group is removed by methods described in the literature such as sodium metaperiodate/ammonium acetate or phenylboronic acid giving the compounds of the invention (Scheme 9).

When the R3 group of the alpha amino acid 6 is not hydrogen the required amino acid is prepared from the carboxyl protected amino acid by reductive amination of the free amino group with an aldehyde and either sodium cyanoborohydride or sodium triacetoxyborohydride or similar reagent (Scheme 10) This is followed by protection of the amino function and deprotection of the carboxyl function using standard methods to give the required amino acids. The carboxylic acid is protected as an ester such as methyl, benzyl or tert-butyl. The amine is protected with a standard protecting group such as tert-butyloxycarbonyl (BOC), benzyloxycarbonyl (Z) or 9-fluorenylmethyloxycarbonyl (Fmoc). The use of such groups is well known in the art. Where R1 has a reactive functional group such as an amine or a carboxylic acid, this group will also be protected

The nitrogen containing heterocycle derivatives are either known compounds or can be prepared by simple modification of published synthetic routes.

The general methods are further illustrated in the following, non-limiting examples. These examples shall not be construed as a limitation of how the invention may be practiced.
